The Pembrokeshire Coast National Park in Wales consistently ranks among the world's best coastal trails. National Geographic placed the Pembrokeshire Coast Path second in the world's top 10 long-distance paths. Stretching 186 miles from St Dogmaels to Amroth, it passes soaring cliffs, beaches, and small villages entirely within Britain's only truly coastal National Park.
With 240 square miles to explore, the path offers dramatic coastlines, heather-strewn moorlands, steep ridges, plunging river valleys, and dense pine forests. Hikers can tackle the entire route in 10 to 15 days, but over 200 circular walks are available, including half-day, short, and easy access options. Wildlife such as dolphins and puffins can be spotted along the way.
Popular Walks and Highlights
Popular walks include the St Davids Head circuit, the Bosherston Lily Ponds walk, the Dinas Island circular walk, the Porthgain to Abereiddi section, and the scenic circular walk from Saundersfoot to Tenby. The Pembrokeshire Coast Path Authority offers a free certificate to anyone who completes the entire 186-mile trail. Walkers can claim their personalised award by tracking progress and submitting details through the National Park Authority website.
A favourite 6.8km circular route starts at Stackpole Quay, leading over cliffs and down pine-fringed steps to Barafundle Bay, frequently voted one of the best beaches in the UK. The route then follows the rugged coast path westward to Broad Haven South, a golden sweep with dramatic limestone cliffs and the striking silhouette of Church Rock. The return journey passes through the tranquil woodlands of the Bosherston Lily Ponds.
Abereiddi to Porthgain Walk
Another recommended short trek is the 6.3km Abereiddi to Porthgain out-and-back trail, considered easy and suitable for all levels. Starting at Abereiddi, walkers pass the famous Blue Lagoon, a cliff diving hotspot and former slate quarry that operated until 1910. The leftover slate gives the water its stunning aqua-blue hue. The path continues over open grassland with ocean views to reach Porthgain, a fishing port home to the Shed, acclaimed for its fish and chips. Sunday Times writer Giles Coren described their offering as 'light, fresh and crispy,' and chef Stephen Terry praised the 'really good fish and chips.'
